UriTemplateTable.KeyValuePairs 属性

定义

命名空间:

System

程序集:

System.ServiceModel.dll

获取由 UriTemplate 对象及其关联数据构成的键/值对集合。

public:
 property System::Collections::Generic::IList<System::Collections::Generic::KeyValuePair<UriTemplate ^, System::Object ^>> ^ KeyValuePairs { System::Collections::Generic::IList<System::Collections::Generic::KeyValuePair<UriTemplate ^, System::Object ^>> ^ get(); };

public System.Collections.Generic.IList<System.Collections.Generic.KeyValuePair<UriTemplate,object>> KeyValuePairs { get; }

member this.KeyValuePairs : System.Collections.Generic.IList<System.Collections.Generic.KeyValuePair<UriTemplate, obj>>

Public ReadOnly Property KeyValuePairs As IList(Of KeyValuePair(Of UriTemplate, Object))

属性值

IList<KeyValuePair<UriTemplate,Object>>

一个键/值对的集合，由 UriTemplate 对象及其关联的数据构成。

示例

下面的示例演示如何访问 KeyValuePairs 属性。

Uri prefix = new Uri("http://localhost/");

//Create a series of templates
UriTemplate weatherByCity = new UriTemplate("weather/ state}/ city}");
UriTemplate weatherByCountry = new UriTemplate("weather/ country}/ village}");
UriTemplate weatherByState = new UriTemplate("weather/ state}");
UriTemplate traffic = new UriTemplate("traffic/*");
UriTemplate wildcard = new UriTemplate("*");

//Create a template table
UriTemplateTable table = new UriTemplateTable(prefix);
//Add each template to the table with some associated data
table.KeyValuePairs.Add(new KeyValuePair<UriTemplate, Object>(weatherByCity, "weatherByCity"));
table.KeyValuePairs.Add(new KeyValuePair<UriTemplate, Object>(weatherByCountry, "weatherByCountry"));
table.KeyValuePairs.Add(new KeyValuePair<UriTemplate, Object>(weatherByState, "weatherByState"));
table.KeyValuePairs.Add(new KeyValuePair<UriTemplate, Object>(traffic, "traffic"));

table.MakeReadOnly(true);

Console.WriteLine("KeyValuePairs:");
foreach (KeyValuePair<UriTemplate, Object> keyPair in table.KeyValuePairs)
{
    Console.WriteLine("     0},  1}", keyPair.Key, keyPair.Value);
}

Console.WriteLine();

Dim prefix As New Uri("http://localhost/")

' Create a series of templates
Dim weatherByCity = New UriTemplate("weather/ state}/ city}")
Dim weatherByCountry = New UriTemplate("weather/ country}/ village}")
Dim weatherByState = New UriTemplate("weather/ state}")
Dim traffic = New UriTemplate("traffic/*")
Dim wildcard = New UriTemplate("*")

' Create a template table
Dim table As New UriTemplateTable(prefix)
' Add each template to the table with some associated data
table.KeyValuePairs.Add(New KeyValuePair(Of UriTemplate, Object)(weatherByCity, "weatherByCity"))
table.KeyValuePairs.Add(New KeyValuePair(Of UriTemplate, Object)(weatherByCountry, "weatherByCountry"))
table.KeyValuePairs.Add(New KeyValuePair(Of UriTemplate, Object)(weatherByState, "weatherByState"))
table.KeyValuePairs.Add(New KeyValuePair(Of UriTemplate, Object)(traffic, "traffic"))

table.MakeReadOnly(True)

Console.WriteLine("KeyValuePairs:")
For Each keyPair As KeyValuePair(Of UriTemplate, Object) In table.KeyValuePairs
    Console.WriteLine("     0},  1}", keyPair.Key, keyPair.Value)
Next

Console.WriteLine()

注解

表中每个 UriTemplate 实例都有与之关联的数据。 KeyValuePairs 属性包含键值对的集合，其中键是 UriTemplate 实例，值是与 UriTemplate 关联的数据。 值仅可以在调用 KeyValuePairs、MakeReadOnly(Boolean) 或 Match(Uri) 之前添加到 MatchSingle(Uri) 属性，否则会引发 NotSupportedException。
